Speed corrected using Cool Edit Pro:
- joined wavs using 'Open Append'
- speed/pitch adjusted using 'Pitch Bender'
The proper pitch was determined by comparing to a guitar tuned to A=440.
d1 through d3t04 adjusted -23 cents
encore d3t05 adjusted +67 cents
The whole show needed the same adjustment, *except for the encore*. The encore looks like the same source as the rest, but the pitch is clearly different. The -23 cents correction doesn't bring it in tune like the rest of the show. A -33 cents correction does bring it into tune, but then Dark Star is in the key of Ab, while it's always played in A. I highly doubt they actually played it in Ab, and Jerry sounds awfully sluggish. With this in mind, I found that raising the pitch +67 cents brought it into A, and Jerry sounds normal again.
My guess (just a guess), is that the encore was transferred from a DAT at a different time than the rest of the show, or using different equipment or settings, and a 48khz > 44.1khz conversion was not done properly, introducing the new pitch problem for the encore. I'm fairly certain that it is correct now though.
